Write Keywords to webp files?

[pixeldroid.000]

I see that .xmp files are written for the keywords of webp images. Is there no way to write them into the file?
DallE images are written in that format, so if I can't write the keywords to the file, I'll need to convert to png or jpg before assigning keywords.

It looks like I can use the IMatch batch converter to convert existing webp w/metadata and the keywords will be written to the files during conversion - is that correct?
Thanks.

This seems to be an error in the configuration of IMatch somewhere. ExifTool's -listwf lists WEBP as a writable format, so IMatch should embed XMP. I'll have a look over the weekend.

I don't remember anything specific, but webp is a not widely used Google format.
an't Dally output standard image formats like PNG or JPG?
